A difference in histogram between RT and ART

Hi folks! Where does the difference (clipping) in the histogram between the two programs come from, considering the default settings in both?


Its not the same pipeline I don’t think and some of the profiles might be tweaked and I’m sure there could be other nuances that Alberto could explain…I think RT uses Prophoto as a working space and ART uses Rec2020 if I recall…in anycase its not a one to one between the two…Art also has modified the tone curve module and I think it will offer at different result than RT by default… also the default HLR is not the same…

The curves look a bit different by default
